I've been thinking about that recently too. I would imagine that the sacrifice required for the sins of the entire world would be something so great that no human could endure it, hence the need for a godly saviour. But everything we read in the Bible surrounding Christ's death is able to be endured by a mortal man.

Let's start with your question title. For the sake of argument let's turn it around and ask "Why would God not be allowed for forgive us?" The problem lies in God's idea of justice. We could spend a lot of time one this one, but let's keep it it simple:

In order for Him to actually be just, he has to administer justice. In order for justice to be adminstered the proper recompense has to be made for any wrong-doing. We know that the only way to pay for sin is death:

So we have to die. Or somebody has to die for us. The only person qualified to do that is Christ. The why is a subject for another question. Let's skip to what Christ did. When he was on the Cross he took upon himself the full wrath of God against all our sins.

Isaiah 53:4-5 (ESV)
Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God, and afflicted. But he was pierced for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his wounds we are healed.

God chose to crush Him. The pain inflicted by the Romans was nothing compared to the weight of that wrath. Even humans can endure the torture of crucifixion for the amount of time Christ did ... longer in fact. The difference was that while the physical act was in progress he also bore an infinite amount of punishment from His own Father. How does that work out for those who believe in Him?

Romans 5:9 (ESV)
Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God.

To round this out I would point out that from a Reformed Protestant perspective, the notion that anything the hands of men could inflict upon Christ, no matter how brutal the Romans were could do anything to change God's ability to do or not do something is considered heretical. What Christ endured at the hands of the Romans an in crucifixion is both symbolic of a spiritual reality that was going on behinds the scenes, but also real in that that it put the rulers and authorities of this world to open shame while at the same time setting the stage for his physical resurrection to demonstrate his victory over death.

Colossians 2:14-15 (ESV)
[God] by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him.

It's important to remember that there were two separate things happening here. The Crucifixion was only the end of the Atonement, which needed to cover both aspects of the Fall: sin and death.

When Christ was taken by the Roman soldiers, he wasn't still at the scene of the Last Supper, where Judas had been before he left to go betray him. He went up to the Mount of Olives, to the Garden of Gethsemane, and it was there that he took upon himself the sins of the world. He had done everything the Father asked of him thus far, but it was at this one point alone that we ever see any hint of hesitation, when he pleaded, "if it be possible, let this cup pass from me, nevertheless not as I will, but as thou wilt."

Here we have the Perfect Man, who has literally never sinned in his life, being asked to take upon himself the spiritual punishment for all the sins of the world. That's a pretty horrible thing, when you think about it, and it was difficult even for a God to bear. "And his sweat was as it were great drops of blood falling down to the ground." It's hard to imagine what that could possibly be like. Some extreme ordeals, such as childbirth with complications, have been known to cause a very small amount of blood to leak through the skin like sweat. To have it happen generally surely means that something unprecedented is taking place, and to have the subject survive the experience is a miracle in itself!

But he did survive it, paying the price for our sins that we would not have to if we would repent. After that he was taken, betrayed and tried in a sham trial, condemned and sent off to his death on the cross. This was necessary since, even though he had already paid for our sins, there was still death to deal with. So he allowed them to crucify him, giving up his life voluntarily and not having it taken from him (John 10: 18) as evidenced by his sudden death while crying with a loud voice--most victims of crucifixion died slowly of exhaustion, and this would have been impossible ordinarily.

He had to give up his life so that he could take it again, conquering death and unlocking the Resurrection for everyone. It's important to remember that "as in Adam all die, even so in Christ shall all be made alive." (1 Corinthians 15: 22) That part wasn't our fault, so it's paid for unconditionally, for everyone. But our sins are our own choices, so we have to choose to have faith in him, repent of our sins and live according to the law of the Gospel to have them washed away in his blood.

"difficult for even a [sic] God to bear". However, keep in mind that Jesus put off the nature of God to become incarnate as man. While on earth he functioned as a man with the power of the Holy Spirit, not as God.

@Jonathan: I'm sorry. I didn't figure references would be necessary in this specific case, as I stuck to material that's pretty familiar to anyone who knows the story of Jesus.

It was not his suffering that cause the forgiveness, but the sacrifice. Had he been beheaded, all the scriptures regarding his sacrifice would be just as valid.

However the way that he died was to fulfill prophecy:

John 19:36-37 (NIV)
These things happened so that the scripture would be fulfilled: “Not one of his bones will be broken,” and, as another scripture says, “They will look on the one they have pierced.”

The method of the death itself is not significant (outside of it fulfilling prophecy and allowing him a chance to forgive the thief on the cross). It is the sacrifice he made that allows for the sins to be forgiven

Hebrews 10:14 (NIV)
For by one sacrifice he has made perfect forever those who are being made holy.

John 19:36 - You would think a couple bones in the hands and feet were broken; the tarsals and metacarpals or w/e. A nail might pass through the hand if pierced in the right spot, but not likely the feet, given the size of the nails. Do you have any insight to that?

Jesus' death did not "allow" God to forgive us. Were that the case, God would be subject to some external law that says "someone must die for sin".

Instead, God Himself decided that this would be the best way to accomplish His purposes. He could have said that forgiveness could only be available to left-handed people who pray the rosary in Hindi...but He didn't.

The question is, "What is God trying to accomplish?". From what I can tell, it all boils down to this:

But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.

Jesus' death did not "allow" God to forgive us...it is the best way for God to DEMONSTRATE His love.

Many people attempt to see in the physical pain and suffering of the crucifixion that Jesus paid for our sins. While his death was much more physically painful than most, the sins he bore were for the whole world.

1 John 2:2 And he is the propitiation for our sins: and not for ours
only, but also for the sins of the whole world.

The Father placed on Jesus this sin that we all deserve so that payment could be made.

2 Corinthians 5:21 For he hath made him to be sin for us, who knew no
sin; that we might be made the righteousness of God in him.

In death Jesus took our sins and paid the price.

1 Peter 2:24 Who his own self bare our sins in his own body on the
tree, that we, being dead to sins, should live unto righteousness: by
whose stripes ye were healed.

Jesus can offer forgiveness of sins because he paid the price for all sin. He also has the right to judge those who reject forgiveness because he made payment for all those sins.

Jesus' death was brutal. However, we may not even be able to understand exactly what having the sins of the whole world placed on him actually meant.

When the Father looks at us who have received the forgiveness of our sins by faith in Jesus, he does not see our sin anymore but the image of the Son he loves.

Romans 4:7-8 Saying, Blessed are they whose iniquities are forgiven,
and whose sins are covered. Blessed is the man to whom the Lord will
not impute sin.

27 Then the governor’s soldiers took Jesus into the Praetorium and gathered the whole company of soldiers around him. 28 They stripped him and put a scarlet robe on him, 29 and then twisted together a crown of thorns and set it on his head. They put a staff in his right hand. Then they knelt in front of him and mocked him. “Hail, king of the Jews!” they said. 30 They spit on him, and took the staff and struck him on the head again and again. 31 After they had mocked him, they took off the robe and put his own clothes on him. Then they led him away to crucify him.

Recall that in the Old Testament, God gave instructions to Israel on how to atone for their sins through the sin offering. No longer do we have to sacrifice a goat or a bull, as the price has been paid through Jesus Christ, the Lamb of God.

13 For if the blood of bulls and goats and the ashes of a heifer,
sprinkling the unclean, sanctifies for the purifying of the flesh, 14
how much more shall the blood of Christ, who through the eternal
Spirit offered Himself without spot to God, cleanse your conscience
from dead works to serve the living God?

Hebrews 9 (NKJV)

What granted us God's forgiveness wasn't so much that Jesus endured through pain and suffering, but rather that He offered Himself up for sacrifice.

ANF01 - Clement 1st. ltr. to Corinth) Though your sins
reach from earth to heaven, I and though they be redder than scarlet, and blacker than sackcloth, yet if ye turn to Me with your whole heart, and say, Father! I will listen to you, as to a holy people.” 40 Comp. Isa. i. 18.
BLXX Isaiah 1:18

come, let us reason together, saith the Lord: and though your sins be as purple, I will make them white as snow; and though they be as scarlet, I will make them white as wool.”

Before God was manifested on Earth through Jesus, the Hebrews received forgiveness of sin from God. After the crucifixion people still receive forgiveness of sin from God. The Redemption paid by Jesus through the incarnation, the passion, and the crucifixion, washed all mankind of original sin, which had stained man since Cain and Able were born. We are all now washed in the blood of Christ. But when we sin, we must still ask God for forgiveness, and must believe we have received it.

Jesus had His own explanation of the consequences of keeping the laws.

Jesus said:Mt. 5: 17* ¶ Think not that I am come to destroy the law (Torah), or the prophets: I am not come to destroy, but to fulfill. 18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. 19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven. 20 For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.

And: He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
